This extension only works on the Jira Website and only on the specific Backlog View starting with https://*.atlassian.net/jira/software/. If you're using a different Project Type this extension will not work.
The extension does not work out of the box, you need to first configure in Board Settings displaying extra fields under the Card Layout tab. Make sure you add the Status field as the first Extra Field for both the Backlog and Active Sprint sections.
UPDATE (v1.0.2): We now load all of the project statuses from Jira - all of your projects custom statuses should now be stored and color-highlighted correctly.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
